Nuova Simonelli Mac 2000 - Boiler continues to fill up

Went to steam the milk and had no steam, knowing the problem is the boiler is probably full of water started to run water from the boiler via the water spout. Slowly steam came back. Turned espresso machine on/off to try and reset system but notice the boiler continues to fill up with water. Guessing a valve has build up or what? Where do I begin to look. Our water has 2-3 grains of hardness. Help!

I had the same problem of the boiler filling up all the way with water and the water was coming out of every hole in the machine. Turn the machine off, drain the boiler completely,
MAKE SURE VALVE #2 is CLOSED, this is the one under the drip pan all the way to the left. Turn on the water supply to the system and turn the system ON. The cup warmer on top will come on and stay on for anywhere between 10 to 20 minutes..... let it be,,, do not turn it OFF,, it will go off automatically. That should do it!

Water smell

You may have some residue inside the steam pipe from previous uses (e.g. milk). If you know how to remove the steam pipe, this will be easy to clean. Otherwise, you could try a pipe cleaner (depending on the type of steam wand).

You can also try running the steam pipe into some water, but be careful not to overheat the boiler (consult your manual... it may say you can't steam continuously for more than a minute, or even less).

I opened up a business and there was a simonelli mac 2000 there for me to usd. the previous owner never cleaned it or kept up on the maintnecse of the machine. so i am trying to fix that now so i can use...

if the water smells really bad you might have gotten milk in the boiler and if thats the case you will have to totally disassemble the machine and clean every part with milk cleaner to remove any trace of milk on the boiler side. if it just seems like dark brown water it could be that it was left on for a long time with out replentishing the water lvl in the boiler.

Burnt smell is coming from steamer wand

Boiler is contaminated with milk, check the water from the tea valve, if it smells the same or has swimmers, boiler needs to be descaled, if no floaties then removes steam wand and soak in purocaff for a few hours, then clean. Always flush ssteam wand before and after every drink.

Milk frothing wand will not opporate

Check the end of the steam pipe, it might be blocked. If not then the machine is block where the pipe to the steam valve sits on the boiler.

Steamer is not getting hot enough.

Try using the milk clamp on the tube going into the milk.Tightening it will make your milk hotter.
Your steam wand however, is a different problem.
First, check in the programming that the steam temp. is 125 celcius.
If it is, and none of the tubes from the steam wand to the boiler valve are blocked, your boiler temp. sensor may be faulty, in which case, you will need to replace that.

Boiler does not refill properly

Chances are, your level probe (rhs of the boiler) is dirty/scaled.Then the probe is always earthed and does not allow water in as it thinks it's always full.
Take it out and clean with wire wool(obv with no pressure in the boiler).It should have a red wire attached to it.
When you refit it, make sure the part inside the boiler faces down.
